pci_create_legacy_files – create legacy I/O port and memory files
Synopsis
void pci_create_legacy_files(struct pci_bus *b);Arguments
b
-
- bus to create files under
Description
Some platforms allow access to legacy I/O port and ISA memory space on a per-bus basis. This routine creates the files and ties them into their associated read, write and mmap files from pci-sysfs.c
On error unwind, but don’t propagate the error to the caller as it is ok to set up the PCI bus without these files.
